Canoe leaves for no reason???

Dries · Dec 2, 2016

Hey guys
This is a northerlight autoflower
12 days old

So it looks like he is showing symptons of head stress but the temperature has never been over 30°C(26°C on average). Could it be to much light ? I kept 250w hps at 40 centimeter. Is that to close ?

mine do the same thing with too much light, they get over it as they get stronger, your taco/ canoe is slight, if they fold all the way in, or start flipping over,, raise the light some,, it also tends to happen more with the KUSH strains

some people discuss "vapor pressure" when talking about canoe/taco,,, also upping the air circ helps

30 degrees Celsius at that age is a bit warm . Drop ya temp and it should come right .

Is that tin-foil for a reflective ? Room could be at 30 but that reflective surface could be creating hot spots ?

Could be wrong lol

No temp's are around 26°C on average when i put my termometer next to the leaves. I hung my lamp at 60 cm just now.

Yes have a desktop fan shaking the plant a bit. The tin foil is the only thing that keeps that 250w from lighting up my room maybe il can replace with carboard later (cant afford a tent right now)

cardboard is fine,, get some thats white if you can, flat white reflects light very well,,, many of us just paint our walls

I'm by no means an expert, but I think your humidity is too low for the temperature you're maintaining.

Yeah i ment to say that i never had any heat waves. That could explaine why he has canoe leaves from heat stress. (never over 30°C)

It looks like you guys are right i look up vapor pressure difict. I found this thing. Tells us that temp's are to high for humidity. OR humidity is to low for my temp's. Thanks a lot. (Orange is what you need to have.)
